Avalung installed on a Dakine Pack
The Avalung is a great invention. You can install this model into pretty much any backpack that has a hydration sleeve type of pocket. All it takes is a little macgyvering and some thought. I got some extra tubing at homedepot similar to what the avalung is made out of to make the exhaust come out at the bottom right of the pack. Works great, though i don't intend to use it at all costs! Its best to not get in avalanches.
